Input vs. Output

Divide the output power by the input power and
multiply by 100%.

For example, if you are getting 55 watts output with
100 watts input then (55/100)X100% = 0.55 X 100% =
55%.

How much output power that you get for any given input
power depends on many factors including the frequency
of the signal.  Generally, with tubes, the higher the
frequency the less efficient the amplifier.  You might
get 70% efficiency at 80 meters and 55% efficiency at
10 meters.

Is there a calculation to figure equivalency for input
watts to output watts?
